Multivariate Testing (MVT)

Quick answer

Multivariate Testing (MVT) is a process where multiple variables on a webpage are simultaneously tested to determine the best performing combinations and layouts. Unlike A/B testing that tests one change at a time, MVT allows you to test numerous changes and see how they interact with each other.

Key takeaways

  • Multivariate Testing (MVT) helps define how an experiment is planned, run, or interpreted.
  • Clear terminology reduces confusion between marketers, analysts, designers, and developers.
  • Documenting it before launch makes results easier to trust and compare later.
